This beautiful handmade knife is shaped entirely from fiber optic glass. You know, the stuff that gives us super fast internet. A knifemaker used a process called knapping, a throwback method of shaping stones into useful tools, to form it.

Knapping is considered art, and I'd totally agree with this if I didn't think the knife sort of looked like Jello. Beautiful, sweet Jello that could stab you. You can buy your own fiber optic knife for $165. [Make via Crunchgear]
